Future Technology Devices International Ltd.
FT8U100AX USB Compound Hub Controller
Overview
The FT8U100AX USB hub and peripheral controller is specifically designed for implementing a wide
range of USB hub devices including those with embedded functions such as Ir remote controls, IrDA
and wireless communications, monitor controllers etc.. The device includes the USB repeater and hub
controller blocks together with an embedded EMCU micro-controller and many associated peripheral
blocks to perform the embedded functions. Included is support for legacy devices such as PS/2
keyboards and mice, serial and parallel ports and a master/slave Access Bus ( I²C ) controller for
monitor applications. Firmware is in a low-cost external OTP ROM which allows maximum flexibility
for many different product configurations.
With its 7 downstream ports and support for self powered or bus powered power sources and gang
switched or per-port switched USB power management the FT8U100AX USB hub represents a very
wide ranging and flexible solution for most USB hub requirements whilst its low external part count
keeps manufacturer’s product cost to a minimum.
The FT8U100AX’s wide ranging capabilities make it the ideal choice for application areas such as
stand-alone hub boxes ( self or bus powered ) with value added functions such as Ir multi-media
wireless remote and game-pad controllers, USB monitor-hubs with extended Ir capabilities, USB
keyboard hubs etc. The FT8U100AX uses 3.3 volt process technology which lowers power
consumption and reduces electrical noise emissions thus making it easier for products using this device
to conform to FCC and CE emission requirements.
